Through a conversation on (b)(6) 2017, a company representative came to know of a patient who on (b)(6) 2017, had a hybrid ablation surgical procedure simultaneous with ep catheter ablation.The surgical ablation was done first with the surgeon getting subxiphoid access and the ep doctor did the ep catheter ablation to follow via access through the groin using the biosense contact force ablation catheter with the patient being heparinized with an unknown amount.Approximately 2 weeks post procedure, the patient presented at a different facility with chest pain where apparently, air was found in the pericardium.The patient was then transferred to the facility where the original procedure had taken place and a contrast study was done.An atrioesophageal fistula was determined and the patient went directly for surgery.Once in surgery, they could not find anything to repair.The patient died a few days later.The exact date of the patient expiring is not known and an autopsy was not performed.
